Neuroendocrinology of Human Scalp Hair Follicles: Growth Hormone-Releasing Hormone Stimulates Hair Growth and Controls a Fully Functional Intrafollicular Hypothalamic-Pituitary-Somatotropic Signaling Axis

GHK-Cu peptide injections are discussed for hair growth, but users report mixed results and suggest focusing on DHT management first. Some users combine GHK-Cu with treatments like Minoxidil and Dutasteride, but emphasize its benefits for skin rather than hair.

The conversation is about the use of peptide therapies for hair loss, specifically GHK-CU, ZN-Thymulin, and PTD-DBM. The user is seeking feedback on the effectiveness of these treatments from those who have tried them.

Peptides, specifically GHK-Cu, are being considered for hair growth benefits, such as increasing blood flow to the scalp and preventing hair follicle shrinkage. A user reported starting GHK-Cu after hearing it made a friend's hair thicker.

Peptides like GHK-Cu are discussed for hair regrowth, with mixed results; some users report no regrowth, while others notice thicker hair. Topical application is common, and proper sourcing and mixing are emphasized.

The conversation discusses potential hair loss treatments focusing on stimulating IGF-1 at the follicle level using growth-factor cocktails and engineered peptides, such as Acetyl Tetrapeptide-3, Copper Tripeptide-1, Oligopeptide-20, Thymosin-β4, and Palmitoyl Tetrapeptide-7. It suggests that device-assisted delivery methods like microneedling may enhance effectiveness.

Various hair growth treatments were discussed, including microneedling, bimatoprost, setipiprant, stemoxydine, PGE2, CB-03-01, WNT Beta-Catenin upregulators, KY19382, topical estrogen, IGF-1, GH, MK-677, oral castor oil, fisetin, resveratrol, cetrizine, and lactic acid. Users shared experiences and sources for these treatments, with some expressing interest in topical solutions and others noting the lack of FDA approval or scientific evidence for certain options.
